Just a little info from my experience. If you here the clicking when you unlock your car, you will need to change the shaft. That sound is the motor trying to rotate the shaft but running into resistance. This may be because of the needle bearings, or the gears that interact with the motors gears.

@Jbonly21 Жыл бұрын
Thanks, I had to test all of my modules in the starter circuit, in the end I found out I had power coming in to the DME, but no power from the DME to the shaft motor. Bmw drop the ball by not putting protection between the DME and the shaft motor, so if the shaft motor goes bad, it back feed directly back to the DME.

We bought a used 2013 X5 V6 with a bad engine. We bought & installed a used engine, crank but no start, couldn't figure out why. We brought it to bmw dealership, they charged $150 diagnosis & got it start. They said power supply connector for DME is unplugged & many other connectors loose. We didn't think anything was loose. Anyway we agreed to pay $370 more for further diagnosis. They said valvetronic motor, fuel rail pressure sensor, oil pressure sensor, intake air pressure sensor are all bad. We still wonder how they got it start in the first place.
@Jbonly21 Жыл бұрын
They probably reset the Valvetronic motor and that’s how they get it started. It was probably stuck, cause it fails slowly over time.

Hi thanks for sharing! I have e90 and I'm getting 2a3f dme valvetronic actuator power supply & 2A38 valvetronic monitoring sluggish movement. I just tryin to decide if i can just do the needle bearings or if i need a new eccentric shaft.. already got DME fixed, but scared to burn up pin again if ecc shaft doesn't move enough. Was ISTA free?? Suggestions welcome. Can't find much info on E90 eccentric shaft, it is a little different, but also the same. Thanks
@Jbonly21 8 ай бұрын
If you have a N54 or N55 it’s about the same, my bearings wasn’t that bad. I might be able to get away with replacing just the motor. You should remove the valve cover and check visually the condition of the cams and shaft. Also depends on your mileage.

No start, my Valvetronic motor was bad, based on the research I did, it’s recommended to replace the shaft as well. With a job that big there’s no way to know what parts you really need with out tearing it down and doing an inspection. I am not a fan of taking a car apart and then waiting on parts. So I just bought everything that was recommended.

Man I have a n55, and the first diagnosis said code is Valvetronic disabled. So firstly, what if you replace only the servomotor and then try the relearn test plan but fails. 2 weeks later.. the car does not crank or start. The diagnosis showed second time said starter is dead and servomotor is too. Will it be okay to replace only servomotor the second time?
@Jbonly21 Жыл бұрын
Yeah, shouldn’t be a problem replacing just the servomotor if that’s what the problem is. If you replace it with a OEM part, I would just go back in and recheck everything. Make sure you have the car on a charger when running the relearn, also you have to be connected to the internet for it to work.
